Heavenly Father, thank You that I am Your blood-bought child, and that nothing can snatch me from Your hand, for You are my Saviour and I have been transferred from the kingdom of darkness into the kingdom of Your dear Son, Who is the light of the world. Thank You, that I have been forgiven of my sins and covered in Christ’s own righteousness, and thank You that I have been baptised into Christ and set free from slavery to sin and Satan, for which I praise and thank Your holy name.
